I sure hope those ballots are secure so the Rats can't fill in the Hillary box. If examination of those ballots shows so much as a pencil smudge in her box, they will call it "voter intent" to vote for her. Here in NM I personally know several people so disgusted with both selections that they left it blank or voted for Johnson.
I'd have a hard time believing Trump's people aren't on this like Rosie O'Donnell on a toilet seat. They'll have watchers at every point.
